Hanna is right. This is a serious shortcoming in QBO. The memo/description field is ... not. The field heading is a lie. It is not both the memo and the description; the description is simply omitted. Also, there is no report available as you describe. The transaction reports are either Transaction by Supplier or Transaction by Date and neither provide the descriptions. Even selecting "splits" only enters the word "split" and does not include the split information in the report.
